I know how you feel somewhat with that pain, many years ago I walked a little walkathon for walk america, I think it was like 5 miles, I had not conditioned myself prior to this and I did not wear the right shoes for this either. Needless to say later on I could hardly walk. I went to the doctors and he put me on crutches it hurt so bad. He said that I had stretched my achilles tendon, I used to have problems with them every once in a while it would flare up in both feet/ankles. So I know that it does hurt. It has been a long time for a flare up (knock on wood). Just thought I would share that with ya so you know that there is someone out here who can somewhat relate. Have a great day sabrina
